• It is a dangerous excercise to operate each crane functions un-necessarily fast. Regulate the
operation to the adequate speed for each operation.
• The accelerator pedal should only be used to control the crane operation while the machine is
stationed. During traveling operation, use of this pedal is strictly prohibited; otherwise it may
cause an accident due to an operation error which may lead to serious personal injury.
• Always reduce speed of operations at beginning and
ending, and use low speed and high speed as applicable
for respective loads, as well.
• The engine speed is set by the fuel control dial and the
value is given a priority; thus the speed will not be slower
than the value even when the foot is released from the
pedal. For the accelerator pedal control, use the fuel
control dial to set the minimum engine speed required, in
advance.
Use both of the fuel control dial (1) and accelerator pedal (2) as
applicable for proper control of the operation speed.
[1] WHERE THE OPERATION SPEEDS ARE UNVARYING：
Set the fuel control dial (1) adequately to the operation speed.
• (a) Low idling (MIN): The position that the dial is turned
counterclockwise (left) to the end.
• (b) Full throttle (MAX): The position that the dial is turned
clockwise (right) to the end
[2] WHERE THE OPERATION SPEEDS ARE VARYING：
1. Set the fuel control dial (1) to the minimum speed of the
operation
2. Use the accelerator pedal (2) to adjust speed to correspond to
the operation load.
• (a) Low idling: Release you foot from the pedal.
The engine speed is slower and operation speed of each
crane function is slower, accordingly. In this condition, the
minimum engine speed regulated by the fuel control dial (1) is
available.
• (b) Full throttle: Use the accelerator pedal.
The engine speed is faster and operation speed of each crane
function is faster, accordingly.
